<h1>DAT (4mm) Technology</h1>

<h3>Overview</h3>

First generation DAT (DDS-1 (Digital Data Storage)) drives store 2.0
GB per tape and transfer 0.183 MB/s. With 2:1 data compression, the
capacity is 4.0 GB and speed is 0.366 MB/s.

<p>

Second generation DAT (DDS-2) drives store 4.0 GB per tape and
transfer 0.366 MB/s uncompressed. With 2:1 compression, the capacity
is 8.0 GB and speed is 0.732 MB/s.

<h3>DAT Media</h3>

A DDS-2 cartridge costs $15-20.
